Our new paper provides contemporary population estimates of four #petrel species on #MacquarieIsland - the first since #InvasiveSpecies eradication. Antarctic Prions are most widespread and we found many new colonies of recolonising Blue and Grey Petrels.

About 1/3 of all seabirds nest underground. They’re challenging to survey. We studied 4 spp of burrowing #seabird on one island. Different approaches were needed to estimate populations of #petrels despite their similar ecology. Transects, targeted searches & #modeling@_jezbird
1) Despite #petrel surveys using the same cue - burrow entrances - different types of survey and analysis are needed when species' abundances and patterns of distribution vary markedly.
Link to yesterday's Guardian (thanks Mark Spalding) on stranded assets as society moves from fossil fuels. Here is 2014 Horizon scanning paper. This just isn't being smug - is another example of how horizon scanning routinely identifies forthcoming changes

Critical Swift Parrot habitat resides in lutruwita / Tasmanian logging coupe DN007B. Add your name to tell Logging Minister Guy Barnett to make it a true sanctuary & declare it “Swift Parrot Important Breeding Area” not a clearfell. #SPIBA https://t.co/aDVyH6OU1y
Joined @BobBrownFndn surveying Critically Endangered Swift Parrots in Tasmania's old growth forests under imminent threat of logging. This bird visiting its nest is in forest due to be clear-felled in 2022.
